Question

我有以下代码，我使用Spring的@Transactional注释和JDBC模板，它不回滚事务。我使用了随机文件名和表名。我试图删除外键id的行，然后在名为“data”的数据库表中插入相同id的记录。但是当我测试时，我看到如果插入中有错误，则删除不会被回滚。我对Spring很新，所以任何帮助都会受到赞赏。

TestService.java

   @Service
   public class TestService {

      @Autowired
      TestRepository testRepository;

      @Transactional(rollbackFor={Exception.class})
      public void insertData(List<Data> dataList, Integer fkId)
         throws Exception {
         testRepository.updateData(dataList, fkId);
         //do some other stuff
      }
 }

TestRepository.java

 @Respository
 public class TestRepository {

    @Autowired
    @Qualifier("dataJdbcTemplate")
    private NamedParameterJdbcTemplate dataJdbcTemplate;

    @Transactional(rollbackFor={Exception.class})
     public void updateData(List<Data> dataList, Integer fkId) 
        throws Exception {

         String deleteId = "DELETE FROM data where 
        fk_id = :fkId";

         dataJdbcTemplate.update(deleteId, new 
           MapSqlParameterSource("fkId", fkId));

         String sql = "INSERT INTO data(fk_id, column1, column2)"
            + " VALUES(:fkId, :column1, :column2)";

         SqlParameterSource[] batch = 
SqlParameterSourceUtils.createBatch(dataList.toArray());
    dataJdbcTemplate.batchUpdate(sql, batch);


 }

database.xml

    <tx:annotation-driven transaction-manager="transactionManager"/>
    <bean id="dataJdbcTemplate" 
      class="org.springframework.jdbc.core.namedparam.
      NamedParameterJdbcTemplate">
      <constructor-arg ref="dataSource"/>
    </bean>

您应该尝试启用事务传播。

@Transactional（rollbackFor = {Exception.class}）不回滚事务
